IPv6 test with EC25

IoT Modules LTE Standard Module
1

Hi,

I have a Quectel EC25- E module connected to my Linux Board, with IPv4 i can able to access internet.
Now i want to test IPv6 with EC25. Can some one help me on below queries.

  1. Does EC25-E supports IPv6?
  2. Procedure for testing IPv6 with EC25 module?

Thanks & Regards

Connect using “IPV4V6” as the PDP_type argument in your AT+CGDCONT command.

You can test using the URL http://test-ipv6.com/

Hi snowgum,

Thanks for the reply.

Unfortunately my Linux board doesn’t have a GUI to test with the suggested URL.
Can you please share the procedure for testing ipv6 with commands.
Queries:

  1. Where is DHCPv6 server exists in cellular networks?
  2. How we assign a global ipv6 address?

First query your modem with AT+CGPADDR

5

Here is the output
AT+CGPADDR
+CGPADDR: 1,“100.114.238.225,36.1.73.0.51.25.229.164.0.1.0.1.215.196.138.151”

6

this is your IPv6 address, 36.1.73.0 corresponds to 2401:4900, this is a global address

Try AT+CGPIAF=1,1,1,0 and then AT+CGPADDR again, you should get a better output.

7

Followed your commands and below is the output

AT+CGPIAF=1,1,1,0
OK
AT+CGPADDR
+CGPADDR: 1,"100.124.56.49,2401:4900:3764:9C0F:0001:0001:E6B7:2783"

OK

when i try to ping6 “2401:4900:3764:9C0F:0001:0001:E6B7:2783” this ipv6, it is showing Network is unreachable
and even ipv6 is not displaying in the wwan0 network configuration.

wwan0     Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

                RX bytes:1270 (1.2 KiB)  TX bytes:8561 (8.3 KiB)

Any thing more needed for testing ipv6 between two gsm modules.

I suppose you either need to configure DHCPv6 client or manually add the address obtained to the interface and add default route for v6.

Tried with udhcpv6 client

root@rb-imx6ul:~# udhcpc6 -i wwan0
udhcpc6: can't get MAC
udhcpc6: can't get link-local IPv6 address

After assigning an ipv4 address with udhcp client link-local IPv6 address is removing
How to get a mac address for wwan0? It is always showing zeros.

10

I have no experience with this client. Try adding the address manually or try another client (if available for your platform).

11

With the below command i got the ipv6 addresses and i need to assign them to wwan0.

root@rb-imx6ul:~# qmicli -d /dev/cdc-wdm0 --wds-get-current-settings 
[/dev/cdc-wdm0] Current settings retrieved:
           IP Family: IPv6
        IPv6 address: 2401:4900:376e:edee:c404:6063:560a:456e/64
IPv6 gateway address: 2401:4900:376e:edee:690d:f86b:265c:6a1a/64
    IPv6 primary DNS: 2401:4900:50:9::65
  IPv6 secondary DNS: 2401:4900:50:9::55
                 MTU: 1500
             Domains: none

Can you please tell me the commands on how we can assign ipv6 addresses manually with ifconfig/ip

12

something like
sudo ip a add 2401:4900:376e:edee:c404:6063:560a:456e/64 dev wwan0

You can also try qmi-network script.

With that command i can able to assign ipv6 global ip. But when i try to assign ipv6 gateway it is throwing below error

root@rb-imx6ul:~# route -A inet6 add default gw 2401:4900:22e2:fe42:819c:4587:3751:dfb9/64 dev wwan0
route: getaddrinfo: 2401:4900:22e2:fe42:819c:4587:3751:dfb9/64: -2
route: resolving 2401:4900:22e2:fe42:819c:4587:3751:dfb9/64

Even with ip command too unable to assign gateway.

Any suggestions on this.
